Study of Mechanochromism of Photonic Crystal Treated Knitted Fabrics
Photonic crystals based on internal structure can respond to the external environment by changing the structure,which have a very broad prospect in smart color-changing.In order to meet the requirements of simple and convenient fabrication of intelligent fabrics,a mechanochromism photonic crystal film was prepared and com-pounded with black knitted fabrics to obtain intelligent color-changeable textiles.Then the surface morphology,optical properties and mechanical properties were studied.The results show that the prepared smart color-changing fabric has a blue shift with the increase of strain,and the structural color is angle-dependent,and the mechanical stability is also excellent.The smart fabric has great potential in anti-counterfeiting and motion monitoring.
